Congrats on your upcoming newborn! A few of us have done this exact JB baby haul trip before, and honestly Manjaku Baby Mall is usually the first stop we recommend, it carries big brands like Medela, Drypers, MamyPoko, and Anmum all under one roof, so you can tick off most of your essentials in one go without running around. One of my mum friends swears by it for the pricing, especially on diapers and formula which we all know add up fast. Tateh and Fabbie are also worth a walk-through if you have time, as some mums find slightly different selections there that complement what Manjaku carries. For your newborn clothes and the smaller bits, just go with a rough list so you do not overspend, the prices are so good it is easy to overbuy!
